El Salvador hydraulic cylinder,stainless steel cylinder manufacturer,stainless steel cylinder
(El Salvador stainless steel cylinder,produced by Hebei Hengyu company）
stainless steel cylinder are widely used in El Salvador，because of excellent temperature resistance，no transmission clearance，powerful torque.So our company has designed stainless steel cylinder for customers from El Salvador.
The stainless steel cylinder body is commonly made of No. 20, 35, 45 seamless steel pipe, and the steel pipe is honed or rolled to achieve the roughness requirement within 0.4μm. The low pressure stainless steel cylinder can use 20 steel pipe, and the high pressure stainless steel cylinder can use 45 steel pipe.
The internal leakage of the stainless steel cylinder is an important indicator to measure the quality of the stainless steel cylinder: the internal leakage of the stainless steel cylinder will reduce the volumetric efficiency, increase the temperature rise of the oil, affect the positioning accuracy of the stainless steel cylinder, so that the stainless steel cylinder can not accurately and stably stop in a certain position of the stainless steel cylinder, so it is one of the main indicators of the stainless steel cylinder.
When installing the piston rod, it is necessary to ensure that the direction of the connecting head at the top of the piston rod should be consistent with the direction of the stainless steel cylinder head adn the earring (or the middle hinge shaft), and ensure the straightness of the whole piston rod during the advance and return process to prevent the phenomenon of rigid interference and causing unnecessary damage.
The advantages and disadvantages of the stainless steel cylinder: the surface of the stainless steel cylinder by painting, coating protection treatment, bright luster is not easy to rust, all raw materials of the stainless steel cylinder through the top heat treatment, high manufacturing precision, belongs to the precision machinery, has a simple structure, stable quality, high mechanical efficiency, easy to achieve automation and many other advantages. However, hydraulic technology also has the shortcomings of oil leakage, oil temperature change affecting the control of running speed, noise, expensive cost and high maintenance cost.
What is the role of the cylinder on the plastic mold? The oil cylinder plays a great role in the mold, one is that the core distance is very large, or because of the mechanism of the product, only the oil cylinder is reasonable or more cost saving. Let the side core be extracted before opening the mold. Hot runner is mainly based on the product, sometimes customers require to use hot runner, the price is more expensive, but there are many benefits. It can save raw materials and shorten the molding cycle.
What is a constant velocity cylinder? What is the difference between hydraulic cylinder and constant velocity cylinder?
The constant speed cylinder should be the same as the speed of the piston rod extension and withdrawal cylinder is called the constant speed cylinder. The difference between it and the ordinary hydraulic cylinder is that the ordinary hydraulic cylinder only has a piston rod extended out, and the general extension speed is slow and the recovery speed is fast, because of the relationship between the effective area. Effective area of piston chamber > Effective area of piston rod chamber. The effective area on both sides of the constant speed cylinder is the same, because there are piston rods sticking out at both ends. The application of constant speed cylinder is most common in grinding machines.
